Akai GX-230D reel-to-reel

AC Servo Capstan Motor and GX head characteristics assure  complete tape travel stability and long lasting performance. Automatic and Manual Reverse Playback.

Integrated Akai Quality Features for Unparalleled Performance

New AC Servo Motor

The new Akai AC Servo Motor employed in this model for direct capstan drive is equipped with 114 gears on both the rotor and stator sides and a detector coil and magnet are built in on the stator side for a completely new pulse detection system. With this system, pluse detection is made only once every 114 pluses instead of at each pulse for greatly increased pulse output.

Symmetrical head Block, Impedance Roller, and tension Arms for even tape travel in both directions.

For perfectly equal tape speed and even tape tension is both directions, the head block layout is of symmetrical design and the machine is equipped with an impedance roller and tension arms. These features function together as integral parts of this GX Head, AC Servo Motor system for unparalleled stability and long-lasting quality performance.

Automatic and Manual Reverse Playback.

Automatic Reverse Playback is as simple as applying a piece of sensing foil to the tape at desired reversing point. Manual Reverse Buttons  can be operated at any time during plauback.

All GX heads

One each GX Forward Playback, GX Reverse Playback, and combination  GX Recording/Erase head guarantees long lasting performance. As is well known, the core of these heads are made of single crystal and are mounted and set in glass. The wear-free characteristics of these materials permit a perfectly lineal head gap for a "focused field" system and optimum head-to-tape contact which results in a wider dynamic range with excellent Signal-to-Noise ratio.
